The present invention relates to improvements in valve mechanisms, and more in particular to novel valve structures adapted for use in'conjunction with gas burners and the like.

Among the objects of the present invention is to provide a novel valve mechanism embodying in its construction an inlet means and aplurality of outlet means, in combination with a valve member incorporating noval structure having means for establishing fluid flow between the said inlet means and any one of said outlet means and for establishing a different rate of fluid flow between said inlet means and one of said outlet means.

Another object of the present invention is to provide a novel valve mechanism embodying the structure as immediately above set forth, and further including novel means for adjusting the fluid flow from the inlet means to one of said outlet means.

The present invention has as a further object the provision of novel valve mechanism for a double outlet oven valve for use'with gas burners or the like, which provides for full capacity fluid flow from an inlet passageway to outlet passageways and for more limited flow through an auxiliary passageway from the inlet passageway to one of the outlet passageways.

More particularly, the invention contemplates such structure as immediately above defined in an integral housing assembly and in which novel means is provided for adjusting the fluid flow through the auxiliary passageway to one ofthe outlet passageways.

A further object of the present invention'is to provide a double outlet oven valve incorporating novel valve mechanism operated byway of a handle or the like which will provide for the full capacity flow of fluid to either of the two outlet passageways incorporated in such structure, and which further is constructed 'to'embody novel means to provide for a smaller predetermined flu d flow to one of said outlet passageways when the valve member is moved intoa'nother posit on.

As a further object of the present invention, novel means is prov ded in the valve mechani m for conveniently adjusting fluid flow at a prede- 'termined rate in accordance with desired'operating characteristics for the said burner'or burn- 'ers to which said valve is connected.

In one of its aspects, the present invention contemplates a valve mechanism having inlet and outlet means and novel valve'structure providing for fluid flow at 'diifere'nt rates therebeseatingwithin, the boreof a housing and which has an adjustablemeans, such as a screw orthe like, for controlling-the passage of fluid-through the passageway establishing one of therates of flow when the valve member is in one of its positions.

More particularly, the present invention embodies in its construction'novel adjustable means mountedat one end ofthe valve member which is adapted to be adjustable 'for flow of fluid through the valve mechanism in predetermined quantities.

Other objects, features, capabilities and advantages are comprehended by the invention, as

thereby.

Referring more particularly to the drawing, an embodiment selected to illustrate the present in vention is'showninl igures 1 to5 inclusive as'in- "eluding a housing of valve body 2 formed with "an axially disposed tapered bore 4 extending herethrough and adapted to receive in seated relation therewith valve member 6. The valve mechanism illustrated in the present embodiment further incorporates operating mechanism, generally referred to as 8, conforming substantially to the structure now disclosed in a copending application in the name of Philip S. Harper, filed July 29, 1939, and bearing Serial No. 287,398, and which mechanism forms no part of the present improved structure. This operating mechanism 3, as can very well be appreciated, is for operating the valve member 6 into its various rotative positions through the medium of a shaft, such as l6, controlled by a handle (not disclosed) which is mounted adjacent the outer end thereof whereby the said valve member 6 is easily and readily manipulated to its various positions as indicated.

The valve housing 2 includes the laterally disposed inlet passageway IZ formed by the exteriorly threaded wall M whereby the said valve housing may be connected to a gas supply in a conventional manner. The housing 2 further includes the oppositely disposed outlet passageways I6 and I8 formed in part by the wall structures 26 and 22 and in part by the wall structure (not disclosed) disposed in normal relation thereto and which is formed as integral structure with the said walls 26 and 22. The said passageways l6 and I8 are closed at one end by the closure elements 24 and 26. respectively.

The rotative valve member 6 in the embodiment shown in Figures 1 to inclusive, is formed withan axially disposed bore 26 communicating at one point with a radially disposed passageway 36 and at another point with a radially j disposed passageway 62, the former of which terminates at the periphery of the valve member 6 and the latter of which communicates with the passageway 34 extending across the said valve member 6 and intersecting the periphery thereof.

The valve mechanism further embodies in its construction an axially disposed bore 36 formed in part in the main body of the valve member 6 and in part in the extension 38 and which communicates with the bore 28. The bore 36 is internally threaded to receive the screw member 40 formed with its inner end as at 42 of reduced diameter which is adapted to slidably fit within the axially disposed passageway 28. The screwthreaded member 46 is formed with a slot 44 at its outer end to facilitate rotation thereof and to adjust its inner end. 42 in the axial bore 28 whereby flow of fluid through the radially disposed passageway 32 may be regulated as desired, all as will more fully appear. In order to protect the screw-threaded member All, a screwthreaded plug ie is threaded into the extension 38.

The present valve mechanism as'above described is all incorporated in a structure of unitary assembly and lends itself admirably to incorporation into control mechanism for the burners for gas ranges and the like, and particularly for controlling the flow of gas from the inlet means l2 to a broiler and also to an oven, particularly where high and low adjustment for the broiler is desired. In accordance with the present illustration, the passageway 16 is in communication with the broiler burner, and the passageway i8 is in communication with the oven burner. The improvements incorporated in the present valve mechanism are such as to facilitate the control of gas fiow to the broiler burner to provide for high and low burning (ill characteristics therefor when the valve member 6 is in either one of two positions, and to also provide for the full capacity flow of fluid to the oven burner when the valve member 6 is in another position.

As illustrated in Figure 3 of the drawing, the valve member 6 is in a position with respect to the valve housing or body 2 to provide for predetermined limited flow of fluid from the inlet passageway !2 to the outlet passageway 56. As is quite apparent, the passageway 38 is in communication with the inlet passageway l2 and through the axially disposed passageway 28 is in communication with the radially disposed passageway 32. Since this radially disposed passageway 32 communicates with the passageway 34, fiow of gas to the outlet passageway 16 is accomplished. This passageway through the Valve mechanism constitutes an auxiliary passageway providing for low burning characteristics for the broiler burner, and the quantity of gas passing therethrough is controlled by proper adjustment of the screw member 46. Accordingly, predetermined quantities of gas may pass from the inlet passageway 2 to the outlet passageway 16.

As illustrated in Figure 4 of the drawing, the valve member 6 has been rotated into a position to provide full capacity flow of gas from the inlet passageway IE to the outlet passageway l6, this being accomplished through the medium of the passageway 3 provided in the valve member 6. This position of the valve member 6 provides for the high burning characteristics for the broiler burner, and such may be effected by simple rotative movement of the valve member 6 into another position from that shown in Figure 3 of the drawing.

Where it is desired to provide full capacity flow of gas from the inlet passageway IE to the outlet passageway is, the valve member 6 may be rotated into a third position, such as shown in Figure 5 of the drawing, whereby the passageway 34 of the said valve member intercommunicates with the said passageways l2 and I8 to provide for such flow. In the illustration, the flow of gas through the valve mechanism provides for high burning characteristics for the oven burner. According to the invention, therefore, a valve mechanism of unitary structure is provided wherein gas may be supplied to the oven burner or to the broiler burner for high or low burning characteristics.

The valve mechanism may take the form as shown in Figures 6 and 7, if desired. The said valve mechanism in this modified version of the invention comprises a valve housing of substantially the same construction as shown in the first described embodiment except that a by-pass passageway 48 is provided which communicates with the inlet passageway l2 and the axially disposed bore 4 of the valve housing. The valve member 50 which seats within the bore 4 conforms substantially to the valve member 6 hereinabove described, and includes an axially arranged bore 52 communicating at one point with the radially disposed passageway 54 corresponding to the passageway 32 of the embodiment of Figures 1 to 5 inclusive, and at another point with a radial- 1y disposed passageway 56, which in turn is adapted to communicate with the by-pass passageway 48 when the valve member 56 is in one of its positions. I

As in the previously described embodiment of the invention, valve member 66 is further formed with anin'ternally threaded axially disposed bore 58 formed in part in themainbody of the valve 50 and in part in the extension 60 and which communicates with the bore 52. Mounted in the threaded bore 58 is ascrew-threaded element 64 which has its inner end 66 of less diameter adapted to be slidably received within the bore 52 to adjust flow of gas from the inlet passageway I Z-through the passageways43 and 56 to the bore 52, and thence through the passageway 54 to the outlet passageway 16. This is accomplished through the medium of the passageway 68 conforming to the passageway 34 of the previously described embodiment, and which, in the position as shown in Figure 7 of the drawing, intercommunicates with the passageway 54 and the passageway l6.

In this modified'valve structure, as in the previousillustration, the outlet passageway l6 communicates with a broiler burner, so that by virtue of the structure of the elements herein described, low burning characteristics for the broiler burner may be secured when the valve member 50 is in the position as shown in Figure 7 of the drawing. High burning characteristics for both the broiler burner and the oven burner are obtained when the valve member 59 is in positions corresponding to the positions of valve member 6 in Figures 4 and 5, respectively.

As will be clear from the abovedisclosure, the

unitary valve assembly is of simple construction wherein the parts may be readily fabricated at low cost and which effectively provide, through the medium of a single unit, control of flow of gas to an oven burner and to a broiler burner for high and low characteristics. l'nv addition, the improved valve mechanism incorporates an adjustable feature for flow of gas to the broiler burner which may be adjusted to predetermined rates to secure the desired low burning characteristics and which is conveniently disposed for adjustment between the housing wall structure which provides for the outlet passageways l6 and I8.

While I have herein described and upon the drawing shown illustrative embodiments of the invention, it is to be understood that the invention is not limited thereto but may comprehend other constructions, arrangements of parts, details and features without departing from the spirit of the invention.
